The 677B series differential pressure transmitters are designed to measure pressure ranges as low as 0.1% with an accuracy of ±0.4%. The 677B series is used in building energy management systems, environmental pollution control, oven pressurization, laboratory and fume hood control, HVAC, and VAV applications. These transmitters feature 15 psid overpressure, reverse polarity protection, and EMI/RFI protection. Internal regulation allows the use of an unregulated DC power supply. A NEMA 4 enclosure allows for flexible mounting positions, and the overall mounting label simplifies installation.
Calibration options are available as an accessory.
● NEMA 4 housing enables a range of use outdoor or indoor where water is present
● High accuracy at low pressure ranges provides exceptional measurement for insuring tight-control and minimizing costly out of specification conditions
● Use with unregulated DC power permits easy access to electrical supply reducing costly power conditioning and wiring
